This invention relates to a novel cultivator shovel construction wherebythe usual function of a shovel is performed and in addition weeds arecut, the ground is mulched and is left level. I

An important object of the present invention is to provide a novelconstruction whereunder the surface of the soil so as to cut the weedsand work and mulch the ground leave the latter level.

Another object is to provide a novel construction wherein the plows areeasiento guide and the shovel is capable of universal use in existingstructures of. cultivators inasmuch as it may be attached to round orsquare cultivator shanks. Various additional objects'and advantages andwill be pointed out or become apparent from i a consideration of thedescription following taken in connection with accompanying drawingsillustrating an operative embodiment. 1

In Figures l, to'5, a conventional shank of a cultivating machine isshown at 10, which .is adapted to carry acultivator shovel. The shankshown is square in'c'ross section and is provided with a slot 11throughthe same adjacent the lower end r l The cultivator shovel isshown at l2rbeing preferably curved as shown but generally ofconventional form. Such shovel, ,1 2 by means or a'rivet 13 or the like,islrigidly secured to an attaching plate 1 1 of the form bestillustrated in Figure 8. A bolt 15:1 a1so entends throughtheshovel 12,being rigid 3 7 therewith and" secured thereto or loose, .as

Said plate 28 has abolt hole 30 therethrough, which is preferably round as shown, throughwhich bolt 15 extends and beneath which a nut 31 and washer 32 may beapplied to the bolt. The plate 28 asat 34. In lieu of two blades 27, asingle has a V-shaped flange 83 to surround the rear hlede may be pfoyided for either right er-left hand use',1asi'11 eultivatingcorn or thellke.
